一、检定前的准备液相色谱仪首次检定的时间比较长,所以需要提前一天跟客户沟通,询问检测器类型,详细了解平常做样所使用的流动相。若流动相为正相,则需要转换成反相系统(根据JJG705-2014《液相色谱仪检定规程》使用水或甲醇作为流动相)。由于正相系统的流动
First, the pre-test preparation LC for the first time longer test, so need to communicate with the customer one day in advance, ask the detector type, a detailed understanding of the usual use of the mobile phase. If the mobile phase is in positive phase, it will need to be converted to an inverting system (using water or methanol as mobile phase according to JJG705-2014 “Liquid Chromatography Calibration Protocol”). Due to the flow of the normal phase system
